DRV8424P - Overview

Dual motor H-bridge driver DRV8424P​

The DRV8424P dual H-bridge motor driver breakout is a compact, efficient solution for driving two DC motors or one bipolar stepper motor. It supports motor supply voltages from 4.5V to 33V, and delivers up to 1.5A continuous current per H-bridge (with heatsinking), making it ideal for medium-power motor control applications.

With built-in current regulation, adjustable decay modes, and low-power sleep mode, the DRV8424P driver enables flexible and energy-efficient motion control. It is easily interfaced with microcontrollers like Arduino and supports PWM input for speed and direction control.
